|Scientists Say Adios to La Nina : Image of the Day - NASA -- Image and animation by Greg Shirah, NASA GSFC Scientific Visualization Studio|
This image shows the difference in sea surface temperature (SST) between current conditions and a normal SST for this time of year (red is 5 degrees C above normal, blue is 5 degrees C below normal,) combined with sea surface height anomaly (shown by the shading of the ocean surface,) and sea surface wind anomaly (represented by arrows.) Current SST is measured by the Tropical Rainfall Measuring Mission Microwave Imager, while sea surface height anomaly was measured by TOPEX/Poseidon, and the wi...

|Microwave Imager Measures Sea Surface Temperature Through Clouds : Image of the Day - NASA -- Image courtesy TRMM Project, Remote Sensing Systems, and Scientific Visualization Studio, NASA Goddard Space Flight Center|
This image was acquired over Tropical Atlantic and U.S. East Coast regions on Aug. 22 - Sept. 23, 1998. Cloud data were collected by the Geostationary Operational Environmental Satellite (GOES). Sea Surface Temperature (SST) data were collected aboard the NASA/NASDA Tropical Rainfall Measuring Mission (TRMM) satellite by The TRMM Microwave Imager (TMI). TMI is the first satellite microwave sensor capable of accurately measuring sea surface temperature through clouds, as shown in this scene...

|Massive Solar Flare: Image of the Day - NASA -- Images courtesy sohowww.nascom.nasa.gov/ Solar & Heliospheric Observatory|
A massive solar flare erupted from the surface of the Sun at 9:51 UTC on October 28, 2003. The solar flare persisted for more than an hour, peaking at 11:10 UTC. Associated with the flare was an ejection of a billion tons or more of gas from the Sun's tenuous outer atmosphere, or corona. Both the flare and the coronal mass ejection accelerated electrically charged particles to very high energies and hurled them at near the speed of light directly toward the Earth...
